WHEEL.

SPECIFICATION forming part of Letters Patent No. 255,720, dated March 28, 1882.

Application filed September 20, 1881. (No model.) l

To all whom it may eoncernz' i Be it known that we, WILLIAM T. CHRISTY and EDWARD C. SHERIDAN, of Newark, in the county of Essex and State of New J ersey, have 5 invented a new and useful Improvement in later-Wheels, of which the following is a specification. i

Our invention relates to an improvement in water-wheels, whereby we avoid loading our 1o wheels with any dead-water, and we have no backwater to diminish the power, and We largely reduce the friction; and it consists in a plug valve or gate, a chtite, and a waterwheel with bottomless buckets riding upon a plate or table in a suitable cylinder crease.

Figure l is a side elevation, partly in section. Fig. 2 is a horizontal section on line a: m, Fig. 1. Fig. 3 shows the wheel inverted. Fig. 4 is a detailed view.

In our construction, A is a cylindrical case, or it may be globular or other form, containing a horizontal water-wheel, B, hung on the spindle C, having suitable bearin gs, from which spindle power may be communicated for any 2 5 purpose.

The buckets D have no bottom, but are made to ride on the plate or table E, which for an instant becomes a bottom. This table is attached to one side of the inner surface of 3o the case and so arranged that the lower end of the buckets in their revolution will just sweep the upper surface of the table, and while the buckets are passing over it, at the time charged with Water, the table becomes a bottom forthem, holdingthe water long enough to have them get the full force of the charge, and then it escapes as the buckets pass oft' from the table, and. leaves them for the rest of the circuit unencumbered. The water is fed in from the chute F, in which is a plug 4o gate or valve, G. The opening is a notch, H, cut out of one side of the plug, and the turni ing of this regulates the flow of water or entirely cuts it off. When the water is fed on it passes through the chute and immediately fills the buckets (see Fig. 2) and gives motion to the wheel, the buckets at the time of filling riding upon the table E; but the movement of the wheel instantly carries the buckets oft' from the table, aud, having uo bottom, leaves 5: the water to drop unobstructed into the basin I or tail-race below. Thus it will be seen that all the force of the Water is expended on the buckets, and then is instantly discharged, leavto obstruct the action of the wheel. This becomes, then, a. very simple and effective water wheel or motor. Some modification of the form of gate and of feeding the water to the wheel may be employed and the same effect 6o be produced.

We claim- 1. The wheel B, having the bottomless buckets D and working in the case A, in combination with the plate or table E and chute F, 65 substantially as and for the purpose specified.

2. The combination of the case A, wheel B, buckets D, table E, chute F, and gate Gr, slibstantiall y as and for the purpose set forth.
